Set access to member profiles

NSDictionary *changes = @{
    @"groupID": groupID,
    @"lookMemberInfo": @(OIMAllowTypeNotAllowed)
};

[[OIMManager manager] setGroupInfoDictionary:changes
    onSuccess:nil
    onFailure:nil];

OIMAllowTypeAllowed has the value 0 and allows access. OIMAllowTypeNotAllowed has the value 1 and denies access. This setting is independent of permission to add friends from within a group.

After the success callback, reconcile the final state through onGroupInfoChanged: or a new query.
